IMPROVEMENT IN SASH-LIFTS.

Specification forming part of Letters Patent No. 171,249, dated December21, 1875; application filed September 13,1875.

To all whom 'it may concern:

Be it known that I, JOHN SWEET, of the city and county of Providence,State of Rhode Island, have invented certain new and useful Improvementsin Sash-Lifters; and I hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawings forming part of this specication. i

Figure 1 is a view of a windowsash, showing my improved sash-liftersecured to the sides ofthe sash. Fig. 2 is a top view of the same,showing the sash in section.

a; is the curved shtail-shaped projecting arm. b is the base, having twoscrew-holes, by which the same is secured to the sash. l c is thewindow-sash; d, the glass of the window.

Similar letters of reference indicate correspondin g parts. I

The invention has reference to and consists in a metal sash-lifter,formed of a base-plate and projecting arm, adapted to be secured to theside of a windowfsash, and used for the purpose of raising or 'loweringthe sash. .r v

This sash-lifter is intended to be generally used in connection with' aWindow-spring or sash-holder, the object Abeing'to so construct the samethat the same lifter may be secured to either side ofthe sash.

In windows where the v sash is supported by a spring or sash-holder,without balanceweights, the saslicannot b'e raised or lowereduntilthesash-holderis relieved. By placing my sash-lifter close to thelever of the sash-holder, the same maybe released and the sashVsupported by one hand. Sash-holders or Vwindowsprings are secured attimes to one and y at other times to the opposite Side ofthe sash.

Both right and left hand sash-litters are, therefore, required. WideWindows also require a sash-lifter on each side ot' the window, so asstock of each kind, While it s difficult for buildy ers or otherpurchasers to ascertain the number of each kind required, thus causingtrouble and delay to both merchant and purchaser. To overcome thisdifficulty I construct my sash-lifter so that the same may be used oneither side of the sash, making both sides alike or reversible, as isfully shown in the drawings.

My sash-lifter consists of a base having two holes for screws, by whichthe same is secured to the sash, and a curved tishtailshaped projectingarm, under and behind which a finger is passed, so that the same hand bywhich the sash-holder*j is released also supports the sash, while thesame may be placed and secured on either side of the window to thesash.Only one-kind need, therefore, be kept in stock, the same beingreversible, and all annoyance and loss of time is avoided.

This sash-lifter can also be used on windows having the sash balanced byweights,

and materially assist in the raising or lowering ofthe same.

Having thus described my invention, I claim as new and desire to securebypLetterslPatent- As a new article of manufacture7 a reversiblesash-lifter, consisting ot' the hase b and projecting arm c, adapted forattachment to the side of a window-sash, substantially as hereindescribed.
